Our Services

Seamless Cold Worked Tubing

The seamless cold worked tubing available at our factory is custom manufactured, created from raw form solid bar and pierced to convert to mother hollow. Our on-site normalizing process produces suitable tubing for cold working, and after a sulfuric acid cleaning, cold rinsing, and lubrication bath, the specified materials are drawn utilizing a mandrel draw bench with carbide die. The outside diameter, inside diameter, and wall thicknesses are reduced to the required dimensions with resulting high tensile properties, dimensional accuracy, micro structure uniformity and excellent surface quality. Tubing is available in a range of carbon and alloy grades including 1020, 1026, 1030, 4130, 4140 and 4150 among others.        Our experienced tube making process is adapted and modified to produce customer specified components for critical applications. Parts are stress relieved others are quench & tempered followed by rotary straightened for extremely straight tubes and tube ends are then cut to an exact 90° square. Parts are deburred and coated with a rust preventative treatment. Thorough testing methods are employed in process and post production to ensure the highest quality and accuracy levels, including eddy current testing, 100% dimensional tests, straightness, and cosmetic evaluations.
